2. 1. Natural specific T cell immunity in patients with B-cell chronic lymphocytic leukaemia (B-CLL) : (A clinical and immunological study)

   Author : Mohammad Reza Rezvany; Karolinska Institutet; Karolinska Institutet; []
   Keywords : B-CLL; TCR usage; clonality; natural T cell immunity; costimulatory molecules; dendritic cells; cytokines; tumor derived VH-CDR3.;

   Abstract : Analysis of TCRBV (T-cell receptor B variable) gene usage of the T cell repertoire in patients with B cell chronic lymphocytic leukaemia (B-CLL) and age-matched healthy control donors showed that major perturbations were more frequently seen in the CD4+ T cell subset than in CD8 population. Analysis of the CDR3 length polymorphism revealed a significantly higher degree of clonality within the CD4+ and CD8+ T cell repertoire of patients as compared to the normal control population.

4. 2. Structural and Electrical Transport Properties of Doped Nd-123 Superconductors

   Author : Shaban Reza Ghorbani; KTH; []
   Keywords : high temperature superconductors; critical temperature; resistivity; thermoelectric power; Hall coefficient; X-ray diffraction; Neutron diffraction; NdBa2Cu3O7-delta; hole concentration; substitution;

   Abstract : It is generally believed that one of the key parameterscontrolling the normal state and superconducting properties ofhigh temperature superconductors is the charge carrierconcentrationpin the CuO2planes.By changing the non-isovalent dopingconcentration on the RE site as well as the oxygen content in(RE)Ba2Cu3O7−δ, an excellent tool is obtained tovary the hole concentration over a wide range from theunderdoped up to the overdoped regime.
